FIG. 6 is a flowchart for illustrating a method for converting a text into a voice message in a terminal according to an embodiment of the present disclosure.

Referring to FIGS. 2 to 6 , at step S110, the user of the first terminal 100 may open a real time broadcasting channel, and start broadcasting. More specifically, the user of the first terminal 100 may generate the broadcasting channel through a real time broadcasting application. The user of the first terminal 100 may perform a voice broadcasting or a video broadcasting in real time through the broadcasting channel.

At step S120, the processor 150 of the first terminal 100 may recognize the voice of a certain user. For example, the certain user may be the user of the first terminal 100. In some embodiments, the processor 150 of the first terminal 100 may recognize the voice of the user of the first terminal 100 being received in the input/output interface 110 during broadcasting. More specifically, of the audio data being input into the input/output interface 110, the processor 150 may recognize the voice of the user of the first terminal 100, and extract the recognized voice of the user of the first terminal 100.

At step S130, the first terminal 100 may receive an item and a certain text from a guest who entered the real time broadcasting channel that the user of the first terminal 100 opened in real time through the communication interface 140. In some embodiments, at least one or more guests may participate in the real time broadcasting channel, and an item and a certain text may be received from a certain guest of the at least one or more guests. The received item and the certain text may be transmitted to the processor 150.

At step S140, the processor 150 of the first terminal 100 may prepare an algorithm for generating a voice message converted from a certain text into the voice of a certain user. For example, the prepared algorithm may be a data recognition model being used to convert the certain text into the voice message using the voice of the certain user. The data recognition model may be a model that is based on a neural network. For example, the learning models such as a Deep Neural Network (DNN), Recurrent Neural Network (RNN), and Bidirectional Recurrent Deep Neural Network (BRDNN) may be used as the data recognition model, but there is no limitation thereto.

The prepared learning model may be a learning model for generating a voice message converted from a certain text into a certain voice. The learning model for generating the voice message may be a result of learning a correlation regarding a plurality of voices, a plurality of texts, and voice messages converted from the plurality of texts into the plurality of voices, respectively.

For example, the processor 150 of the first terminal 100 may learn a correlation between a certain voice, a certain text, and a voice message converted from the certain text into the certain voice. The terminal 100 may exercise an artificial neural network based on the result of learning, and generate a learning model.

In another example, the terminal 100 may receive a learning model for generating a voice message from the server 400. In this case, the server 400 may generate a learning model that learned the correlation between a certain voice, a certain text, and a voice message converted from the certain text into the certain voice, and provide an application that includes the generated learning model to the terminal 100.

At step S150, the processor 150 of the first terminal 100 may generate a voice message using the algorithm. More specifically, the processor 150 of the first terminal 100 may apply the voice of a certain user and a certain text to the algorithm and generate the voice message. The voice message may be a result of the certain text converted into the voice of the certain user.

At step S160, the first terminal 100 may output the generated voice message. More specifically, the first terminal 100 may output the voice message through the input/output interface 110. Otherwise, the first terminal 100 may output the voice message through the communication interface 140.

FIG. 7 is a flowchart illustrating a method for converting a text into a voice message in a terminal according to another embodiment of the present disclosure.

Referring to FIGS. 1 to 5 and 7 , at step S210, the user of the first terminal 100 may open a real time broadcasting channel, and start broadcasting. More specifically, the broadcasting channel may be generated through a real time broadcasting application. The user of the first terminal 100 may perform a voice broadcasting or a video broadcasting in real time through the broadcasting channel.

At step S220, the processor 150 of the first terminal 100 may recognize the voice of a certain user. For example, the certain user may be the user of the first terminal 100. More specifically, the processor 150 of the first terminal 100 may recognize the voice of the user of the first terminal 100 being received in the input/output interface 110 during broadcasting. Further, the voice of the user of the first terminal 100 may be stored in the memory 130.

At step S230, when the voice of a certain user is recognized for or more than a standard period of time, the processor 150 of the first terminal 100 may extract characteristics of the voice. For example, the characteristics of the voice may mean a voice-specific accent, frequency brand, formant and pitch, etc. That is, voice characteristics may mean the voice-specific characteristics that can form the corresponding voice.

At step S240, the processor 150 of the first terminal 100 may generate a comparison voice based on the extracted voice characteristics. In addition, at step S250, the processor 150 of the first terminal 100 may compare the voice of a certain user and the generated comparison voice.

At step S260, the processor 150 of the first terminal 100 may store the voice characteristics in the memory 130 depending on the result of comparison. In some embodiments, when an error between the voice of the certain user and the comparison voice is not more than a standard value, the processor 150 may store the voice characteristics in the memory. For example, the error may be calculated through a difference of sampling values between the voice of the certain user and the comparison voice. The method for calculating the error between the voice of a certain user and the comparison voice is not limited thereto, and may be calculated using various methods.

In some embodiments, in a case where a noise is recognized as the voice of the user of the first terminal 100 during voice recognition, the comparison voice generated using the extracted voice characteristics may have a large error compared to the voice of the user of the first terminal 100. Therefore, in order to generate a voice that is similar to the voice of the user of the first terminal 100 using the voice characteristics, the processor 150 may perform a process of generating the comparison voice using the voice characteristics, and comparing the voice of the user of the first terminal 100 and the comparison voice.

At step S270, the first terminal 100 may receive an item and a certain text from a guest who entered the real time broadcasting channel that the real time user of the first terminal 100 opened through the communication interface 140. In some embodiments, at least one or more guests may participate in the real time broadcasting channel, and an item and a certain text may be received from a certain guest of these guests. The received item and the certain text may be transmitted to the processor 150.

At step S280, the processor 150 of the first terminal 100 may generate a voice message based on the certain text and the voice characteristics and output the generated voice message. In some embodiments, the voice message that the processor 150 generated based on the voice characteristics may be similar or identical to the voice of a certain user. The first terminal 100 may output the voice message through the input/output interface 110. Otherwise, the first terminal 100 may output the voice message through the communication interface 140.

In some embodiments, the voice recognition unit 151 may analyze the input audio data and distinguish the input audio data into a voice section and a non-voice section. The voice recognition unit 151 may exclude the audio data included in the non-voice section, and recognize the voice of the audio data included in the voice section, and transmit the recognized voice to the model application unit 153.

The model application unit 153 may apply the voice of the user of the first terminal 100 and the certain text received from outside to the algorithm and generate a voice message. In some embodiments, the learning model for generating the voice message may be a result of learning the correlation between a certain voice, a certain text and a voice message converted from the certain text into the certain voice.

The characteristics extraction unit 154 may generate a comparison voice using the extracted voice characteristics.

The comparison unit 156 may compare the voice of the user of the first terminal 100 and the comparison voice. The comparison unit 156 may store the voice characteristics in the memory 130 depending on the result of comparison.

In some embodiments, when the error between the voice of the user of the first terminal 100 and the comparison voice is not more than the standard value, the processor 150 may store the voice characteristics in the memory 130, and transmit the voice characteristics to the voice message creation unit 158.

For example, the error may be calculated through a difference of sampling values between the voice of the user of the first terminal 100 and the comparison voice. The method for calculating the error between the voice of the user of the first terminal 100 and the comparison voice is not limited thereto, and various methods may be used in the calculation.

If the error between the voice of the user of the first terminal 100 and the comparison voice exceeds the standard value, the comparison unit 156 may transmit a feedback signal to the characteristics extraction unit 154. When the feedback signal is received in the characteristics extraction unit 154, the characteristics extraction unit 154 may extract the characteristics from the voice of the user of the first terminal 100 once again.
